Passengers are encouraged to check the flight status with their airline before heading to the airport, especially if they're headed to Chicago.

GSP officials said this is the busiest travel week of the year for them.

The airport recently completed an expansion to its economy lot, which opens up an additional 400 spaces. It costs $4 a day to park in that lot.

They also added luggage cart rentals in those parking lots to help travelers with a lot of luggage get to and from the terminal easier. Those carts can be rented for $2.

The motor club keeping an eye on the highways across the Carolinas predicts there will be a few more motorists on the road for Thanksgiving because of a significant drop in the price of gasoline.

AAA Carolinas said there will be a 1 percent increase in the number of people driving during the four-day holiday. Spokesman Tom Crosby attributes the increase to a 54-cent drop in the price of a gallon of gasoline at North Carolina pumps since mid-September.

Traveling in South Carolina will be even less painful. The average price of $3.13 per gallon there is the cheapest in the country.

Construction projects in North Carolina are suspended during the holiday. In South Carolina, contractors are required to keep all lanes open during heavy holiday travel periods.
